[ELF][MIPS] Add handling for __gnu_local_gp symbol This symbol is a "fake" symbol like "_gp_disp" and denotes the GOT + 0x7FF0 value. llvm-svn: 259781

# Check handling of relocations against __gnu_local_gp symbol.

Always create a .got on mips. The _gp* family of symbols is defined as an offset in .got, and it is not at all clear what should happen when .got is not defined. This will allow some simplifications on how these symbols are handled. llvm-svn: 266063

Don't make _gp absolute. _gp points to a position in the file, so it is not really absolute. It is also simpler to not force it to be absolute, so if there is no strong ABI requirement we should not do it. llvm-svn: 313333
